LOOSE REED-MOTION FOR LOIVIS.

Application led September 29, 1913.

To all whom it may concern Be it known that I, FREDERICK OTT, residing at Conshohocken, in the county of Montgomery and State of Pennsylvania, have 1nvented certain new and useful Improvements in Loose Reed-Motions for Looms, whereof the following is a specification, reference being had to the accompanying drawings.

.n object of the invention is to provide a reed having a fixed set of blades, a movable set of blades alternating with and crossing the fixed blades, means tending to throw the movable set of blades rearwardly within the spaces between fixed blades, and other means operatively engaging the movable set of blades and actuated by a fixed abutment located in the forward path thereof, so that in the forward or beating motion of the lay the two sets of blades will operate together at their points of crossing as one set to beat up the weft threads, and in the backward or reverse movement of the lay the movable set of blades will be moved rearwardly between the [ixed blades. This object I accomplish by the mechanism shown in the accompanying drawings, in which- Figure I, shows the parts in the position which they assume when the lay is retracted and the warp threads separated by the harness, not shown, for the passage of the shuttle, not shown. Fig. II, shows the position of the reed members as they appear in the forward or beating up position of the lay.

l, designates the lay mounted on the layswords 2, in any approved manner. The swords 2, are actuated by the usual connecting rod 3, toward and from the breast beam l, in the manner common to looms. The reed is formed of a series of Xed blades 5, secured in the lay at their upper and lower ed ges in any approved manner, and a set of connected swinging` blades 6, slidably held at the upper edge in a groove formed in the upper bar of the lay and extendlng rearwardly through the rear fixed set of blades,

so that two crossing comb-like structures are formeel.

The lower edge of the swinging set of blades 6, is pivotally connected to a cross bar 7, carried by the upper ends of a series of levers 8, only one of which is shown. These levers 8, are mounted near their lower ends on a cross bar 9, secured to the lower edge of the lay 1. The levers 8, are moved rearwardly to the position shown in Fig. I,

by the contractile springs 10, one only being shown, secured at one end to the lower side of the lay l, and at the other to the lower arms 11, of levers 8. This rearward movement of the levers 8, is limited by stops 15, projecting' therefrom and engaging the under side of the lay 1, as shown in Fig. I.

The levers 8, are moved forwardly to the position shown in Fig. II, by means of an abutment 13, in the form of a cross bar sccured to the loom frame 14e, below and in rear of the breast beam 4:. It will be seen, therefore, that as the lay 1, moves rearwardly, the arms 11, will be moved away from the abutment 13, and the springs 10, will be free to act, and will move the levers S, and the movable set of reed blades 6, rearwardly, so that a combing action is established between the two sets of reeds and the warp threads 17, which are now separated for the passage of the shuttle. As the lay l, is moved forwardly toward the breast beam, the arms 11, will engage with the abutment 13, and move the levers 8, forwardly, so that at the moment the reed is to beat up the weft thread 1S, the two sets of reed blades 5, and 6, will be in the positions shown in Fig. II. In this position the reed blades 5, and 6, cross each other at the beating up l point, as in the type of reed where two sets of stationary crossed blades are employed. The advantage of this latter type of reed is, therefore, present, as well as that of the reed having the movable and fixed set of crossing blades which render the use of all sorts of warps available.

It will be noticed that I dispense with all mechanism such as cams and the like movable devices for actuating the movable blades 6, in the forward direction, since the arms 11, and abutment 13, obviate the necessity thereof.

I'Iaving thus described my invention, I claim:

1. A loose reed comprising a fixed set of blades, a movable set of blades loosely pivoted in advance of the fixed set and extending through the said fixed set at an angle edge of the movable set to move it forwardly and bring its blades to the crossed beating up position with respect to the fixed blades.

2. A loose reed motion comprising a Xed set of blades, a movable set of sprinnf-retracted blades extending through the fixed set at an' Vangle thereto, an actuating device Connected to the free edge of the movable' set of blades, and a fixed abutment in the forward path of the said actuating devine, whereby the two sets of reeds are brought into proper beating-up relation. K

The combination in' 'a loom, with the lay, of a set of fixed reed blades on the lay, an intermediate movable set of reed blades loosely pivoted tothe lay and extending` downwardly and lrearwardly through the lixed set, a lever pivoted between its ends to the lay and to the upper end of whieh the loose reed section is pivoted, a spring throwing the upper end of the lever rearwardly, and a liXedl abutment in the 'forward path ofa portion ot said lever to throw the loose reed section into beating-up position; i

l. The Combination in a loom, with the lay, the breast beam and an abutment between the beam and lay, of a reed Carried by the lay and formed of a fixed set of blades, a loose set of blades pivoted at their upper ends in advance of the Xed set and extending rearwardly between the iXed set, a lever pivoted between its ends to the lower side of the lay .and pivotally connectedat its upper end to the lower free edge of the movable set, a stop extending from the lever to engage the lower edge of the lay, and a spring throwing the upper end of the lever forwardly, the lower end oli-the lever being adapted to engage said 'abutment as the lay moves toward the breast beam;

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this twenty-sixth day of September, 1913. s
